Definitions

  • the invention relates to a component module for a heat pump system of a vehicle, in particular for a heat pump system of a battery-electric vehicle.
  • the component module comprises several components of a heat pump system and is suitable for heating and/or cooling.
  • Heat pumps offer an efficient method of transferring heat energy, which is why they are preferred for use in battery electric vehicles (BEVs). Heat pumps are used to control the temperature of the vehicle interior on the one hand and the vehicle batteries on the other. Controlling the temperature of the vehicle batteries ensures optimal operating conditions, which leads to improved performance and extends the service life of the vehicle batteries. This is important to increase the range and reliability of battery electric vehicles. Controlling the temperature involves changing the temperature either for heating or cooling, whereby the heat pump can use various heat sources and heat sinks in different fluid circuits. For example, starting up a BEV at low outside temperatures first requires heating the vehicle batteries, with ambient air serving as the heat source. During electrical charging and discharging, however, cooling the vehicle batteries may be necessary to counteract overheating due to heat generation. The heat generated in the batteries can be released to the environment via coolant circuits or to heat the vehicle interior.
  • BEVs battery electric vehicles
  • a heat pump system comprises various components that are fluidically connected to one another in a refrigerant circuit. These usually include a compressor for compressing a refrigerant, a first heat exchanger that functions as an evaporator, a second heat exchanger that functions as a condenser and an expansion device to change the pressure of a circulating refrigerant.
  • the heat pump system uses the principle of evaporation and condensation of the refrigerant, whereby heat is transferred in the heat exchangers between the refrigerant and another fluid, for example a coolant in a separate coolant circuit. The coolant is then used to transport the heat to the desired location in or on the vehicle.
  • the heating and/or cooling module described therein comprises as components a compressor with a heat exchanger for heat transfer between a refrigerant and a coolant as well as a storage device for storing refrigerant.
  • the individual components are fluidically connected to one another in such a way that a refrigerant can circulate.
  • the arrangement of the components is oriented along a spatial axis system consisting of an L direction, a T direction orthogonal to the L direction and a V direction which is orthogonal to the L and T directions.
  • the heat exchanger extends with its longest body size or with its body length parallel to the L direction, whereby the compressor extends with its longest body side, which corresponds to the orientation of the rotation axis of the compressor, essentially along the T direction and thus relative to the Heat exchanger is oriented orthogonally.
  • This arrangement enables a space-saving configuration of the components - but requires more installation space in the LV plane spanned by the L and V directions, particularly in the L direction.
  • This arrangement of the components means that the connecting lines, such as the refrigerant line between the compressor and the heat exchanger, must extend over the entire LV plane due to the design, which partially blocks access to other cooling or refrigerant lines and to electrical plug connections. Furthermore, the expansion of the arrangement in the LV plane cannot be achieved without additional brackets, since the heat exchanger must be supported relative to the compressor, which is associated with additional costs and increases the weight of the module.
  • the invention is based on the object of proposing a component module for a heat pump system of a motor vehicle/BEV, which requires an even smaller installation space volume for the arrangement of the various components and ensures better accessibility to refrigerant and coolant fluid lines as well as electrical connection devices.
  • the component module has at least the following components: A compressor for compressing a coolant, wherein the compressor is accommodated in a compressor housing, the body length of which extends along a compressor rotation axis.
  • the component arrangement has a first heat exchanger and a second heat exchanger.
  • the heat exchangers are designed to transfer heat between a refrigerant and a coolant and have a body length greater than a body width.
  • a collecting container for refrigerant is provided in order to store the refrigerant at least partially in liquid form over the course of the refrigerant circuit.
  • a fluid distribution device is provided as a further component, which is designed to influence a refrigerant flow path.

  • fluid interfaces for refrigerants or coolants are referred to as refrigerant fluid interfaces or coolant fluid interfaces.
  • the components are oriented in their arrangement within the component module as follows:
  • the first heat exchanger is oriented with its body length along a first main direction, the second heat exchanger being oriented with its body length orthogonal to the first main direction along a vertical direction.
  • the body length of the first heat exchanger thus extends perpendicular to the body length of the second heat exchanger, there being an air gap between the first heat exchanger and the second heat exchanger in order to avoid a thermal bridge.
  • the compressor housing is oriented with its body length along a second main direction, which coincides with the compressor rotation axis and is offset in a longitudinal direction parallel to the first main direction.
  • the first heat exchanger and the compressor housing are arranged with their body lengths parallel to one another, which reduces an expansion of the component module in the longitudinal direction oriented transversely to the main directions.
  • the two parallel main directions, the longitudinal direction and the vertical direction relate to spatial axes, of in which the two main directions and the longitudinal direction oriented perpendicular to the two main directions can lie in one plane, wherein the vertical axis is oriented perpendicularly with respect to the plane formed from the two main directions and the longitudinal direction.
  • one of the two main directions and the longitudinal direction form a plane, wherein the other main direction is shifted in the direction of the vertical axis.
  • the heat exchangers are essentially designed in the form of a cuboid, which has a body length greater than a body width.
  • the cuboid shape can have two different body widths, which are each smaller than the body length.

  • a The spatial expansion described in the technique which is significantly larger in a single spatial direction in relation to the expansion in other spatial directions, is avoided, thereby advantageously reducing the required installation space volume.
